Thanks for responding Logan and Albea! I appreciate it

Seems like I should get a time for Tina at another vet:

We have taken Tina to the vet for this before, but she was not X-rayed. The only thing the vet did was feel her over and say that it was probably just the typical problem with hips that goldens have. I was kind of stumped at the time that she wouldn't examine her further but I thought there was nothing else she could do, so hearing that she should have been X-rayed and checked more thoroughly is quite... annoying. We also asked about her weight when we were there because I do think she is a lil bit too round, and we asked for special diet food and everything, but all the vet replied with was saying that she didn't think it was worth the bother to make Tina diet when she was so old.

I'll take a look at those links Albea, thanks for showing me them! Oh and BTW, your goldens are all adorable! I was looking at your website and boy are they all gorgeous You must be proud!
